Adds a flag to Listener.new() and register_postdissector() to make C-side
dissectors populate all fields.

As discussed on the ask wireshark site here:

http://ask.wireshark.org/questions/4678/lua-listener-dynamic-fields

one really should expect that all_field_infos() provides all field infos.
However, since this is a performance issue, I've attached a patch which fixes
this but only if the call to Listener.new() or register_postdissector()
includes a boolean true argument to make the C-side dissectors populate all the
field infos.  When this flag is passed in, all_field_infos() provides all the
field infos; when it's not set, it defaults to false and all_field_infos() only
returns the field infos that the C-side dissectors happened to populate each
time, as is done today.
